NON-REFILLABLE BOTTLE.

Specification of Letters Patent.

Patented Mar. 1d, 1911.

Application filed February 16, 1910. Serial No. 544,280.

To all whom 'it may concern:

Be it known that I, LEO J. LOEFFELMAN, subject of the Emperor ofAustria-IIungary, residing at St. Louis, State of Missouri, haveinvented certain new and useful Improvements in Non-Refillable Bottles,of which the following is a specification.

rlhis invention has for its object a simple, durable and eflicientconstruction of non-refillable bottle, the parts of which are soarranged that the bottle may be easily filled with its originalcontents, and may be easily emptied, while at the same time t-heconstruction and arrangement of parts will prevent the relling of thebottle.

With this and other objects in view as will more fully appear as thedescription proceeds, the invention consists essentially in a bottle ofthis characr provided with an improved construction of valve and animproved arrangement of parts, whereby, as the bottle is tilted to pourout its contents, air will be positively forced into the body of thebottle so as to permit the liquid to flow easily out'and unseat thevalve. And the invention also consists in certain constructions,arrangements and combinations of the parts that I shall hereinafterfully describe and claim.

For a full understanding of the invention, reference is to beihad to thefollowing description and accompanying drawings, in which: A

Figure 1 is a longitudinal sectional view of a bottle constructed inaccordance with my invention; Fig. 2 is a perspective sectional viewthereof, the section being taken on the line 2-2 of Fig. 1; Fig. 3 is asimilar view on the line 8 3 of Fig. 1; and, Fig. l is a verticallongitudinal section illustrating a modification.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

Referring to the drawing, the numeral 1 designates the body portion of abot-tle which may be of any size or design and which is provided with aneck formed with an outwardly facing shoulder 2, an outwardly bulgedportion 3 above said shoulder, and a nozzle 4. At the base of the nozzlel, the bottle is formed with an inwardly facing annular shoulder 5.

6 designates a valve seat which is preferably constructed out of arubber ring o-f inverted truncated cone form, the said valve Vseat beingadapted to rest on the shoulder 2, the outer or upper edge of the ringbeing of larger diameter than the shoulder, as clearly illustrated inthe drawing. A valve 7 of porcelain, glass or the like is adapted torest on the valve 6, being shaped to conform to the interior surface ofthe valve seat and being preferably formed with a bulged lower end 8which is designed to project through the valve seat so as to assist inholding the valve in place except when it is unseated by the weight ofthe content-s of the body portion of the bottle. The valve seat 7 isalso formed with a nipple 9 which projects upwardly, as shown, and it isdesigned to hold the lower end of an expansion spring 10 which isinterposed between the valve 7 and the inverted cupshaped lowerextension 11 of a balie crown 12. The body portion of the baiile crown12 iscylindrical, as shown, and is encircled by a packing'13 of rubber,cork or the like, the said body portion of the crown being thereby heldsecurely within the neck of the bottle and against the inwardly facingshoul' der 5 thereof and being formed with outlet openings 111 which aretwo in number in the present instance. The flared lower eX- tension ofthe crown manifestly serves as a delector, so as to preclude thepossibility of reaching the valve by inserting a wire or tmlaol of anycharacter down into the nozz e 4.

The bottom of the bottle is provided with a centrally disposed raisedportion 15 in which an opening 16 is formed, said opening 16 being ofsufficient diameter to admit the passage therethrough of the valve 8with its encircling valve seat 6 and the baille crown 12. The opening 16is filled with a stopper 17 which is preferably rounded on its lowersurface so as to presentno angles whereby it may be grasped andwithdrawn, said stopper in the embodiment of the invention illustratedin Fig. 1 being formed with an upwardly extending Atube 18 whichprojects into the interior of the body portion 1, a packing 19 ofrubber, cork or the like encircling the tube and engaging the walls ofthe opening 16, whereby to securely hold the stopper in place. Thisstopper 17 is formed with an air inlet opening 20 and it contains apiston 21 of glass, porcelain or similar substance which is providedwith a packing ring 22 and which is designed t0 fit tightly andA yetmoveifreely within the tube 15. Above the piston 21 is a preferablycentrally disposed protuberance 24. So far as the upper end 25 of thetube 18 is concerned it is open; but it is normally closed by means of anipple 26 of rubber or the like which is fitted thereover as clearlyillustrated in the drawing and which is provided with a contractedoutlet opening 27, the rubber normally holding this opening 27 closed,but yielding when air is forced upwardly in the tube 18 by therelatively -upward movement of the piston 21.

From the foregoing description in connection with the accompanying'drawing, it will be understoo-d that any form of cork or other stoppermay be inserted in the noz- Zle 4 and the bottle may then be filled withits contents, but only after the parts before described have beenapplied thereto. Before -l the bottle has been filled, thebafile crownis thrust through the opening 16 and worked up intothe neck of thebottle so as to be securely held therein against the inwardly facingshoulder 5 thereof.y The valve 7 is then applied, together with itsvalve seat, the parts being held together in this operation owing to thefact that the valve has the bulged lower extension 8 before mentioned.After the valve Vseat and its valve have been thrust up through theneck, the upper edge of the valve seat will manifestly spring out overthe upwardly facing shoulder 2 so as to securely hold the valve seat inplace 4with the valve in closed position; thereon. The stopper.17 isthen applied, and the packing 19 will then securely hold this part inplace. In the operation of pouring outthe contents of the bottle, thebottle is tilted for this purpose. The weight of the content-s of the Ybottle has not enough tendency to unseat the valve 7 against the tensionof the spring 10 without any pressure from the inside of the bottle, thespring 10 being stronger than the weight of the valve 7 and tending tohold the same against the shoulder 2 at all times. For this reason Iprovide the piston 21 in the tube 8. This piston 21 moving toward theopen end 25 of the tube 18, will force air from the tube into the bodyof the bottle,

e giving the necessary pressure to unseat the valve 7. The contractedopening in the nipple 26 will," of course, permit the air to pass fromthe tube 18 into the body of the bottle, while at the same time theplug'23, with its Y protuberance 24, will tup intoi the nipple and closethe opening 25, should an attempt be made to force liquid through theopenin 2O and by this way attempt to fraudulently llthe bottle.

yIt is to be understood that my invention is not limited to the exactarrangement and proportions of the parts hereinbefore derubber disk or'plug 23 which is pref-v erably formed on its upper surface with ascribed and illustrated in Figs. 1 to 3, but that various modificationsmay be made without departing froln the scope of the invention asdefined in the appended claims, and for example reference is to be hadto Fig. 4, wherein the body portion and valve structure of the bottleare the same as the body portion and valve structure illustrated in Fig.1, but the tube 18a is not an integral part of the stopper 17 a, but isseparate therefrom and is secured in a recess in the stopper by packingof any desired character. vIn this modification also the tube 18HL ismore elongated than the tube 18 before described, and

the opening 25 is formed by a somewhat elongated neck 25a formed on theupper end of the tube; The nipple 26, with its contracted opening 27a,is like the nipple first specified, as are also the air inlet opening20a, the piston 21a with its packing 22a and the plug 28a with itsprotuberance 24. As the operation of this modification is exactly likethe operation in that embodiment of the invention first set forth, nofurther de- `neck with an interior valve seat, a valve arranged to beheld on said seat, the body portion of the bottle being formed in itsbot-- tom with an opening, a stopper fitting in said opening, a tubeextending into the body portion of the bottle from said stopper, thestopper being formed with an air opening leading into the tube, and apiston mounted in the tube and arranged to positively force air from thetube into the body portion of the bottle=when the latter is tilted topour out its contents.

2. A non-refillable bottle provided with an interior valve seat, a valvearranged to be held on said seat, the body portion of the bottle beingformed in its bottom with an opening, a stopper fitting in said opening,a tube leading into the body portion of the bottle from said stopperanipple closing the upper end of the tube and formed with a contractileopening, the stopper being formed with an opening leading into the tube,and a piston mounted to move freely in the tube between the'opening andvits nipple, for the purpose specified.

' 3. A non-reiillable bottle provided with an interior Valve seat, avalve arranged to be held on said seat, the body portion of the bottlebeing formed in its bottom with an opening, a stopper fitting in saidopening,

a tube leading into the body portion of the bottle from said bottle, thestopper being formed with an air inlet openingleading into the tube, anipple closing the upper end of the tube and formed with a contractileopening, a piston movable in the tube, and a plug interposed between thepiston and the nipple for the purpose specified.

4. A non-refillable bottle provided with an interior valve seat, a valvearranged to be held on said seat, the body portion of the bottle beingformed in its bottom with an opening, a stopper tting in said opening, atube leading into the body portion of the bottle from said bottle, thestopper being formed with an air inlet opening leading into the tube, anipple closing the upper end of the tube and formed with a contractileopening, a piston movable in the tube, and a plug interposed between thepiston and the nipple, said plug being formed with a protuberanceadapted to close tbe contractile opening of the nipple.

In testimony whereof I affix my signature in presence of two witnesses.
